Just wanted to let everyone know, finally found what was causing all my engine trouble, hesitation, missing, poor throttle response. Platinum Plugs, with a stock ignition system. I had been told it was a possiblity but as everyone knows the plugs are alot of work to get to.

 

What kind of plugs were they, and what did you gap them at?

 

Let me guess, NGK ? I had same problem with them.

 

I'll say Bosch...

 

Autolite 3 year platinum plugs, real bummer. With costco gas they would foul out real quick, had been using chevron super and the car improved but continued to get worse and worse.

 

just over .035, with the Accel 300 series wires I though you could open the gap a bit, was just a little loose .035, maybe .037.
